high Nessus Plugin ID 181670


The remote name server is affected by a vulnerability vulnerability.


The version of ISC BIND installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the cve-2023-3341 advisory.

- The code that processes control channel messages sent to named calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack memory, causing named to terminate unexpectedly. Since each incoming control channel message is fully parsed before its contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key;
only network access to the control channel's configured TCP port is necessary.By sending a specially crafted message over the control channel, an attacker can cause the packet-parsing code to run out of available stack memory, causing named to terminate unexpectedly. However, the attack only works in environments where the stack size available to each process/thread is small enough; the exact threshold depends on multiple factors and is therefore impossible to specify universally. (CVE-2023-3341)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to ISC BIND version 9.16.44 / 9.16.44-S1 / 9.18.19 / 9.18.19-S1 / 9.19.17 or later.
